IMPROVEMENT IN OIL-CUPS.

Specification forming part of Letters Patent No.

215,632, dated May 20, 1879; application filed October 5,1878.

To all whom it may concern:

Be it known that I, ALDEN D. KILBORN, of the city of Oakland, county ofAlameda, State of California, have invented a new and useful Improvementin Oil-Cups, of whichthe following is a specification.

The invention relates to that class of oilcups used for lubricatingpurposes where a regular flow of oil is required of any certain desiredquantity; and consists of a flanged top and bottom, with an intermediateglass tube or cylinder, of other material, held together by means ofhollow tubes, being connected to said top and bottom, the inside of saidtube being provided with a valve-screw and click-wheel, which forms theprincipal element of my invention.

In the accompanying drawings, Figure 1 shows an elevation of the oil-cupwith part cut away, showing the interior part embodying my invention.Fig. 2 is a transverse sectional view of the same.

In Fig. 1, 2 shows the glass cylinder. 0 is the flanged bottom, providedwith the shank P, for connecting the cup to the bearing to be oiled. eis a hollow. tube, made a part of the bottom 6, and provided withscrew-thread at its upper edge. The cap (I is also, like 0, providedwith a flange, that fits down over 2. The hollow tube d is made a partof cap d, and provided at its lower end with an internal thread thatscrews over e, thus drawing 0. and (Z together, and holding z firmly inits place.

The hollow column or tube formed by e and d is made large at the upperpart, or in part (1.

V The upper part of e is provided with an internal thread, and its lowerpart, that passes.

through c, is also made hollow, the bore of which is smaller than thebore in (1, while P is provided'with a small hole, K.

In the bore of e and d is inserted a valvescrew, 0, which is providedwith a thumb-disk, b, for turning it. A head fills the opening or borethrough d. As shank of valve-screw 0 extends down the bore, it isreduced in diameter, and is provided with a ratchetring or collar, :0,below which is an external thread,

that screws into the internal thread of c, said shank being continueddown at c, and is pro vided with a flat end and conical pin 2', theobject of the flat end being to form a valve, in connection with thestep that is seen at the bottom of the bore in e and the top of thesmall hole K, so that as c is turned by b the threads of c and e cause 0to move up or down, either opening or closing the oil-passages between 0and e. The pin ion the shank 0 enters the hole K, so as to partiallyobstruct the passage of the oil before the end of 0 reaches the seat.

The ratcheted collar 00 is acted upon by the click '0, which is providedwith a knife-edge, that enters the notches in w, and prevents any jar orrattle from moving valve-screw c. The click 2; is inserted through anaperture in the side of tube cl. (See Fig. 2.) Around said tube (7 is aspring, y, that' passes around '11, causing it to click in and out ofthe notches in 00 when it is turned, and holding it from moving whenonce it is set.

The shank of valve-screw c has at its top an acorn-shaped stopper, d,which screws in the supply-hole. By taking d out oil can be poured inthe hole, which extendsdown through the center of c, and passes outthrough the openings of r, from thence into the hollow of d, and outthrough the openings 8 into the oilcup.

What I claim as my improvement is- The combination of the tube formed byd and 0, provided with the spring y and click 1), with the shank 0,provided with the oilaperture 1', ratchet-collar m and screw below, andpin 1', substantially as and for the purposes set forth.
